To all whom t may concern:

Be it. known that. I, Louis C. DICKENSOE, a citizen of the United F tates. residing at Grand lllapids in the Monty of Kent and State of Michigan. ha re invented new and useful improvements in Processes for Treating Diseased or l t.t2'l \0tl Trees. of which the following is a speciliratimi.

The invention relates to the process of treating diseased or decayed trees by means of a filling and has for an object to render the prur-ess more etlirient.

in the process of treating diseased or decayed trees by cutting away matter to t'orm a axity. in which a filling, consistingof a suitable composition or the like is plaretlj the usual method is to entirely till the rarity with a filling. the edges of the'bark around the mouth of the cavity tiring cut at right angles to the outer surface of the bark. 'lherel ore. when the new bark r nnmeut'rs to grow outwardly and around the tillin; at the mouth of the cavity, the edges ml the old' hark are pressed outwardly by the new bark and in consequence thereof recesses are fori'ned between the new bark and the. edge of the old bark, the mentioned recesses being: sutliciently large to harbor bacteria or other germs detrimental to the new bark. Furthermore, theold bark when pressed outward as mentioned so that the. edges thereof project beyond the,eontour of the tree, does not present a neat and effective appearance and in order to overcome these defects I preferably bevel the edges of the old bark in such a manner that when the new bark grows around the mouth of the cavity, said cavity having been previouslylilled with a composition or the like I a solid joint will be formed between the new bark and the edges of the old bark, the

inoutioned joint being smooth and free from recesses so that bacteria or other germs cannot harbor between the new bark and old bark and thus destroy the new bark, while at. the some time the n'lentioned joint will present a. neat and effective appearance.

in order to more fully disclose the invention, reference is to he had to the accomiititlylllfl drawings constituting a part .of this specification, in which similar similar characters of reference denote corresponding parts in all the views. and in which- Figure 1 is a fragmentary vertical sec tional view taken through a tree, showing a the decayed cavity and the manner ot the bark, the cavity being open. Fig. 2 is a similar vertical sectional view showing the cavity provided with a suitable filling and the growth of new bark, a solid joint being formed between the new bark and the old hark.

Referring to the views. the numeral 10 designates the tree and the cavity therein is designiated by the numeral 11. W'henthe cavity has been cleaned and all. decayed matter removed therefrom. the edges 12 of the bark 13 are beveled adjacent the mouth I t of the cavity and the rarity is then tilled with a suitable filling 15. the mentioned filling being any standard composition suitahly adapted for this purpose. \Vhen the fare of the filling, has been properly smoothed down, the edge of the face will aline with the periphery of the body of the tree and consequently when the new bark 1t; commences to grow over the face at the mouth 14, the mentioned new bark will commence at the inner beveled end of the bark 13, thus forming a tight and solid joint; 17 at the point of connection of the new bark with the edges of the old bark and it will be readily seen that by beveling the edges of the old bark as mentioned to provide the solid joint .17, the elements and foreign matter will be prevented from attacking the roof of the new bark 16.

It has been found that when the new bark grows outwardly, it tends by the pressure produced to chip oil the inner tip end of the beveled edge of the old bark and thus as the new bark will readily grow over the chipped otl edge, a still better joint will be formed between the new and old bark, whereas, if the edges of the bark are out; at; right angles to the outer s u fac of the bark, the outward pressure of the n w bark, would force the edges of the old 'ark outwardly, thus presenting an ungraceful appearance, while at the same time, recesses would be formed between the edge of the old bark and the new bark, the said recess constituting a suitable harbor for various germs that lodge in niches in trees and attack the tender portions thereof. By beveling the edges of the old hark as mentioned, when the new bark appears, the new bark will not only connect with the old hark in such a manner as to form a tight and solid joint, but the line of contour of beveling the edges matter is removed fro eased trees, consisting in beveling the edges of the old bark, around the mouth of the cavity that is formed when the decayed the tree, the cavity being closed with a fil ing the face of which will lie adjacent to the beveled edges of the bark.-

'2. Theherein described process of treating decayed or! diseased trees, consisting in removing the decayed matter from the tree to form a cavity, inserting a filling 'in'the cavity-with the face of the filling adjacent the edge of the bark, the edge of the bark being then beve led so that the inner end of the beveled edge will form a joint with the the mouth of the cavity formed by removing the decayed matter from the tree.

4. The herein described process of: treating decayed and diseased trees consisting in beveling the edges of the old bark at a spaced distance from the month of a cavity. in the tree.

In testimony whereof I afiix my signature in presence of two Witnesses.
